2.4. Setting up tank timing
When starting a seeding pass when stationary, preload time allows for
product to be at the openers before moving to avoid gaps in product
application. It is the time in seconds that the seeder needs to run before
moving off and starting to seed after the master switch is engaged. (Not
applicable to tanks with linear actuator drive types.)
This is triggered when the master switch is turned on while stationary.
During preload time, the meters run at the rate based on the manual
speed that has been set. Once preload time has expired, the system
reverts to the selected speed source.
